IMPRVED REFRIGERATOR.

` m The Schedule referred to in these Lettera Patent anc'l making partof the dame.

by a. clock arrangement, as shown in the accompanying drawing, )ofwhich- Figure 1 is a view the iu'side from above, with a part of the topremoved, to show the several parts.

Figure 2 is a transverse section, showing the parts more fully, and theoperation of the several. part-s.

A is vthe cooling-box or refrigerator'.

B is a metal-lined sap-chambenwith numerous perforations in the bottom,to permit the fresh air to be forced freely through it. v

C is a clock-work, with its main spring,r ,'ivinding part @gear-wheels co c", and their complementary pinions d rl' d", the last of which has acrankshaft, e,

, and is attached to the bellows D by the pitm'an f.

The clock-work C is placed in the chamber E at the endof the box A.

The bellows D extends" from the chamber E into the chamber F, under themetal-lined sap-chamber B, and, when worked by the clock-work C throughpitman f, receives the fresh air from the chamber E through the valve g,and forces it, in a strong current, through the hole 71, in the top ofthe bellows D, into the chamber F, and thence through the holes in thebottom of the chamber B, and from which it passes out of the box A,through holes, near the top,

lone of which is shown at t'.

k is one of several holes ,in the box A, to admit Y 'pure air into thechamber E to'supply or feed the bellows D.

The pitman f is fastened to the bellows D by means of the slottedrollerp, whose bearings fr 'r are fast ened to the top of the bellows D,the pit-mau f passing through the slot in vthe roller p, and fastened toit with the piu n.

Near the top of the clock-work C is a stop or catch, m, pivoted at11,with a knob, o, by which it is brought into contact with thegear-wheel c",'to stop the clockwork C when desirable.

Now, by winding the clockwork C, and releasing 'the gear-wheel 0"frcmthe catch m., the clock C moves the crank-shaft e and the bellows Dthrough the pitman f, till it requires to be wound again, which may betwelve hours or a week, as desirable.

By this method a much stronger current of air, and a cooler box byseveral degrees, is produced than can be done with a fan-blower, withthe same power, and many articles are kept much better, even withouticcthan in the close ice-boxes now in common use; as they require aconstant supply of pure air more than extreme cold,'and if desirable,bothean be combined in the .same box. V

What I claim as my'invention, and desire to seA cure by Letters Patent,is

The clock-work C, bellows D, having valve g, and

aperture h,`chamber F, 'with inlets lc, in combination with themetal-lined cooling-chamber B, with apertures o in the bottom, and exitapertures i near the top, constructed and arranged to cperaterin themanner and for the purposes,` described.
